Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 18,283,727, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 18,283,727 | |
| -1 | -18,283,727 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,283,727.
Example:
1 x 18,283,727 = 18,283,727
and
-1 x -18,283,727 = 18,283,727
Notice both answers equal 18,283,727
With that explanation out of the way, let's continue. Next, we take the number 18,283,727 and divide it by 2:
18,283,727 ÷ 2 = 9,141,863.5
If the quotient is a whole number, then 2 and 9,141,863.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 18,283,727 | |
| -1 | -18,283,727 |
Now, we try dividing 18,283,727 by 3:
18,283,727 ÷ 3 = 6,094,575.6667
If the quotient is a whole number, then 3 and 6,094,575.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 18,283,727 | |
| -1 | -18,283,727 |
Let's try dividing by 4:
18,283,727 ÷ 4 = 4,570,931.75
If the quotient is a whole number, then 4 and 4,570,931.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 18,283,727 | |
| -1 | 18,283,727 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 101 | 707 | 1,111 | 2,351 | 7,777 | 16,457 | 25,861 | 181,027 | 237,451 | 1,662,157 | 2,611,961 | 18,283,727 |
| -1 | -7 | -11 | -77 | -101 | -707 | -1,111 | -2,351 | -7,777 | -16,457 | -25,861 | -181,027 | -237,451 | -1,662,157 | -2,611,961 | -18,283,727 |
